Description

Technical Field

[0001] The utility model relates to the technical field of liquid dispensing devices, and more specifically to a high molecular polymer liquid dispensing device. Background Art

[0002] High molecular weight polymer, also known as polymer, refers to a high molecular weight compound composed of many identical, simple structural units repeatedly connected by covalent bonds;

[0003] Polymer preparation is the process of mixing polymers with other solvents or components. According to the properties of the polymer, a suitable preparation box needs to be selected to maintain its stability. During the mixing process, some stirring mechanisms can be used to stir the polymer and other solvents or components so that the polymer can be evenly mixed and fully dissolved.

[0004] The existing polymer dispensing device usually needs to select a suitable dispensing box according to the chemical properties of the polymer, because the polymer may produce chemical reactions during the dispensing process, which will produce pressure or corrosion on the dispensing box, which makes the general dispensing box prone to corrosion or explosion, making it difficult for the dispensing box to adapt to the dispensing work of different types of polymer compounds; at the same time, the existing stirring mechanism is usually a fixed structure, and it is difficult to adjust the position of the stirring blade during stirring, which leads to a poor stirring effect when the dispensing capacity is too much or too little, resulting in low dispensing efficiency and poor mixing effect. In view of this, we propose a polymer dispensing device. Utility Model Content
